如何在代码中设置LinearLayout的高度

Answer 1

设置RelativeLayout的宽高：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grid_item);
relativeView=(RelativeLayout)findViewById(R.layout.grid_item);
new Handler().postDelayed(new Runnable(){
@Override
public void run(){
relativeView.setLayoutParams(new RelativeLayout.LayoutParams(100,200));
}
